. SPINNING AND TWISTI'NG MACHINE.

SPECIFICATION forming part of Letters Patent No. 295,738, dated March 25, I884.

Application filed April 27, 1883. (No model.)

To all whom it may concern: I

Be it known that I, CHARLES A. Oceans- HALL, of the city and county of Providence,

State of Rhode Island, have invented a new and useful Improvement in Spinning and Twisting Machines; and I hereby declare the following to bea full, clear, and exact deseriprequired twist, thus producing a different quality of yarn.

The object of this invention is to overcome these difficulties, and to so band the spindles that they will all be driven at a uniform speed.

.My invention consists in the peculiar construction and arrangements of parts whereby the splndles of a spinning or twisting machine 3 shall each be driven by two or more bands, and

each of said bands in turn shall pass around two or more spindles. as hereinafter described,

] and pointed out in the claims.

vided with a five-groove whirl.

Figure 1 is a view of a section of adrivingcylinder and parts of three spindles, each provided with a three-groove whirl. Fig. 2 is a plan viewof the three whirls shown in Fig. 1. Fig. 3 is a view of parts of three spindles, each provided with a five-groove whirl. Fig. 4 is a view of parts of two spindles, each pro- Fig. 5 is a view of parts of three spin-dles, each provided with a three-groovewhirl connected with ,a double band, so that the three'spindles will be connected and run at the same speed. Fig. 6

is aview showing three spindles provided with four-groove whirls connected by double bands. Fig. 7 is a view of parts of four spindles, provided each with a two-groove whirl, anda band connecting two spindles and driving the same.

In spinning and twisting machines as here- H tofore constructed .the spindles have been driven in various ways. In the single drivthe whirls of the opposite spindles. number of spindles have been driven by one ally been driven by a separate band passing around the driving-cylinder and the whirl 0n of the .spinning-franie, and in two-cylinder spinning-machines, one spindle on each side i of the machine is usually driven by a continuingcylinder machine the spindles have usu one band passing around both cylinders and A ain a b 7 band; but in all these arrangements each spindle has been driven by one band only, unless two bands have been used to drive the spindle, and in all these methods the spindles wereliable to vary in their speed, as the different bands would adhere to the whirls with more or less strain, causing more or less slip. I

The object of this invention is to avoid this slip of the bands on the whirls, first, by passing the bands around the whole or more nearly the whole periphery of the whirl, and by so connectingthe band with two or more spindles, and each spindle'with two or more bands,

that all the spindles in a spinning or twisting frame will be driven ata fixed uniform speed.

In the drawings, A representsthe drivingcylinder; 13 B, the spindles; O G, the whirls, and D D the driving-bands. The direction of motion of l the bands is indicated by arrows,

and the different bands are distinguished by arrows in solid black and arrows provided each with a round disk.

Referring now to the figures in the drawings, it will be seen that in Figs. land 2 the band passes from the cylinder to the whirl of one spindle, thence around the said whirl, and from the whirl of the first spindle it passes around the whirl of the next adjoining spindle, thence back over the first whirl and from it to the cylinder, and that therefore each band passes around the whirl of two spindles, and each spindle is connected with two bands, thus interlacing all the bands with all the spindles. It is obvious that in this method of driving the spindles and in all the modifica tions shown and described the same band may drive two or more spindles on the opposite side of the spinning or twisting machine, although in thedrawings only one side is shown.

Referring now to Fig. 3, it will be seen by seen that in Fig. 5 the grooves in the whirl are wider than usual, and that in Fig. 6 the upper following the arrows that the band from the I driving-cylinder passes first around the upper groove of the whirl on one spindle, thence around the second groove of the whirl on the adjacent spindle, thence around the first whirl in the third groove, thence around the second whirl in the fourth groove, and, after passing around the first whirl on the fifth groove, to the cylinder; but with this five-groove whirl the central loop, d, instead of passing back to the first whirl, may be carried from the second whirl to the third whirl, and so the band extends first around the first whirl, thence around the second whirl, then around the third whirl in the central groove and back to the second and first whirls in the same way to the cylinder, thereby driving three spindles, or sixthree on each side of the framcby one band, and also driving each spindle by three bands, each compensating for any slip in the other, so that all the spindles in a machine must turn at a uniform speed.

Referring now to Fig. 4, it will be seen that five-grooved whirls may be used, in which arrangement the band leads from the drivingcylinder to the first groove of one whirl, thence to the second groove of the next whirl, and thence to the third groove of the first whirl, and so on back and forth from one whirl to the other around the proper groove, finally returning to the cylinder.

Referring now to Figs. 5 and 6, it will be and lower grooves are wider than the two middle grooves; also, that two bands are used to drive the spindles. In Fig. 5 two bands (indicated by the solid black arrow and the diskarrow) extend to the upper groove of the whirl from the driving-cylinder. If we now follow the black arrow of the band on the central spindle, it will. be seen to pass partly around the first whirl in the upper groove, thence around the left-hand whirl in the central groove, from this to the first whirl, surrounding the same in the lower groove, while at the same time the other band (indicated by the diskarrow) passes around the first whirl in the upper groove, thence around the central groove of the whirl on the next right-hand spindle, thence back around the first whirl and with the other band to the driving-cylinder. Thus the two bands drive the central spindle and the two adjacent spindles,while at the same time the central spindle is driven by the bands from the adjacent spindles. In Fig. 6 the double band is arranged in the same manner,with the modification that, in place of the wide central groove, two grooves are used. Fig. 7 illustratesa simple arrangement in which each band drives two adjacent spindleson the same side of the frame, and each spindle is driven by two bands,

each of which nearly encircles the whirl, thus giving a longer bearing 011 the same, and insu ring the more positive driving of the spindle with a slacker band than was heretofore possible. The same'band may extend to both sides of the spinning-machine and thereby drive four spindles, while each spindle is driven by two bands.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1; The combination, with a driving-cylinder and aseries of spindles carrying groovedwhirls, of a series of driving-bands extending from the cylinder to the spindles, the said bands being arranged substantially as described, whereby each band shall drive two or more spindles,and the latter being each driven by two or more bands, substantiallyas and for the purpose set forth. I

2. The combination,with a driving-cylinder andaseriesof spindles carrying groovedwhirls,

of a series of bands extending from the cylinder to the spindles, said bands being laced from one spindle to another, and surrounding or partially surrounding said spindles, each band being arranged to drive two or more spindles, and each spindle being driven by two or more bands, substantially as and for the purposes described.
